Why Topside Attic Insulation Georgetown Is Cedar Park’s Preferred Blown-In Insulation Company

We’ve sealed and insulated over 9,000 homes since 2016, and a significant share of those have been in Cedar Park’s uniform post-2000 subdivisions. The reviews that matter most to us are the ones that mention specific outcomes - a blower-door reading dropping from 4,200 to 2,100 CFM50, a living room holding 4-5°F cooler on 105°F afternoons, no frozen pipes after Uri. Our response time to Cedar Park neighborhoods like Twin Creeks, Ranch at Brushy Creek, and Forest Oaks is typically same-day or next-day because we know the floor plans before we arrive. A technician who has air-sealed one Meritage attic on your street has already mapped the top-plate gaps, can-light penetrations, and duct chases for the house next door. That local pattern recognition saves time and cuts waste.

Every job starts with a written scope and written price - no work starts without it - and ends with a Documented Photo Record plus before-and-after blower-door numbers on applicable jobs. Under Haven Standard: Arrive on schedule, you get a named technician and a text when they are on the way. The 365-Day Done Right Promise applies to all completed work. If it’s not done right, we make it right.

Our Blown-In Insulation Services in Cedar Park

Blown-In Cellulose

We use GreenFiber cellulose for most Cedar Park attic retrofits because it performs better than fiberglass in our 150°F+ attic conditions and settles less over time. Cellulose is treated with borate fire retardant and pest deterrent, which matters in attics where roof rats have been an issue in some Cedar Park subdivisions. A typical full cellulose install in a 2,400-square-foot Cedar Park home runs $2,800-$4,200, including air sealing of top plates and can lights. We dense-pack to R-38 or R-49 depending on your roof pitch and energy goals.

Blown-In Fiberglass

When we do use fiberglass, it’s Owens Corning ProCat or Johns Manville Climate Pro - never the loose, low-density builder-grade product that came with your house. Blown-in fiberglass works well for top-ups in Cedar Park homes where the original R-30 hasn’t completely degraded, or where moisture management is the primary concern. We see this most often in newer Cedar Park builds from the 2015-2020 window where the original insulation is thin but not yet compacted to nothing. Fiberglass top-ups typically run $1,800-$3,200.

Dense-Pack Wall Insulation

Cedar Park’s production builders rarely insulated exterior walls to anything beyond minimum code, and many 2000s-era homes have empty wall cavities or poorly fitted batts. Dense-pack cellulose fills those cavities completely, reducing thermal bridging and cutting air infiltration through the envelope. We access walls from outside through siding gaps or from inside through strategic drywall cuts - whichever preserves more of your finish. Dense-pack wall jobs in Cedar Park tract homes generally fall between $3,500 and $6,500 depending on wall area and access difficulty.

Blown-In Top-Up

This is our most common Cedar Park service. The original R-30 blown fiberglass in your attic has likely compacted to half its labeled depth or less. We don’t just blow more on top - we first air seal, then measure remaining insulation, then top up to spec with cellulose or fiberglass. In Twin Creeks, Ranch at Brushy Creek, and Forest Oaks, we’ve done so many of these that we carry the common floor-plan diagrams on our tablets. A blown-in top-up with air sealing typically costs $2,200-$3,800 for Cedar Park’s standard 2,000-2,500 square foot production home.

Trusted Brands We Service in Cedar Park

We source materials from Owens Corning, Johns Manville, Knauf, and GreenFiber - no proprietary lock-in, so we match the product to your home’s condition rather than pushing whatever’s in the warehouse. For Cedar Park’s hot-humid Climate Zone 2 attics, we typically specify GreenFiber cellulose or Owens Corning ProCat fiberglass depending on whether we’re dealing with a degraded existing install or a clean-sheet retrofit. We stock common densities and treatments locally, so most Cedar Park jobs don’t wait on material delivery. If your home has Icynene or Demilec spray foam from a previous contractor, we can assess its condition and integrate new blown-in work without disturbing intact foam.

Common Blown-In Insulation Problems We See in Cedar Park Homes

• Builder-grade R-30 blown fiberglass compacted to half depth or less. In Cedar Park’s 150°F+ attics, fiberglass loses loft within 10-20 years. The labeled R-value is effectively gone, and what looks like a full attic is often a thin, heat-conducting mat.
• Unsealed top plates letting attic air leak into living space. Production builders in Cedar Park’s mid-2000s boom skipped air sealing at the wall-to-attic junction. Hot, humid attic air streams through these gaps all summer, loading your A/C and undoing whatever insulation value remains.
• Water lines in unconditioned attics with no thermal protection. Cedar Park’s slab-on-grade homes route plumbing through the attic plane. During Winter Storm Uri, these lines froze by the thousands because thin or compacted blown insulation offered no buffer against single-digit temperatures.
• Can lights and duct chases creating thermal bypasses. The same floor plans repeated across Cedar Park subdivisions have the same unsealed penetrations. We template these from job to job, which is why a crew that has done one house on your street works faster and more thoroughly on the next.
